See § Running the due tasks : Running the due tasks 2.2 Installation of the hardware MediCal Pro can be used on any viewing station that runs on Windows NT4, Windows 2000 or Windows XP. The viewing station can contain any number of displays, Barco and non-Barco displays.
E.g., a dual-head board contains two separate heads, and thus two separate video and sync outputs. 3 Data connection: You can control the Barco CRT displays through the USB bus or through serial connection. Serial connection: Connect the displays’ Remote connectors in a loop- through (daisy-chain) configuration to the viewing station’s computer.
Before installing MediCal Pro 1 You must have Administrator privileges to install the software. 2 If there are older versions of MediCal Pro or MediCal Control installed on the PC, remove them. Please refer to the § “Uninstalling MediCal Pro”, further in this chapter.
3 From the Start menu, select Settings > Control Panel. 4 Double-click on the Add/Remove Programs icon. 5 Select MediCal Pro from the list box at the bottom of the Add/Remove Program Properties dialog. 6 Click on the Change/Remove... button.
Page 27
4 If the system contains no Barco flat panel displays, nor Barco CRT displays connected to the USB bus, MediCal Pro will notice that there is no configuration set up in the program yet. It will ask if you want to log in as Advanced user, to set up the configuration.
Please proceed with § Setting up the configuration , “ Setting up the configuration “. If you have MediCal Administrator installed, select Yes to continue. MediCal Pro will start a Wizard to set up the server. Please proceed with § Connection to MediCal Administrator , “ Connection to MediCal Administrator “.
Page 29
3 The Wizard will start searching for the server on the network. Click on Next to start the search. If the Wizard does not find the server or if there are problems to register to the server, you will have to exit the Wizard. Contact the system administrator to solve the problem.
Page 30
5 The drop-down list shows all medical facilities connected to MediCal Administrator on the server. If the facility to which this viewing station belongs, is not in the list, you should exit the Wizard by clicking on Cancel. The medical facility should be added from within MediCal Administrator.
Page 31

They are all connected physically, by means of cables and connectors. An example of a medical viewing station consisting of one PC with four imaging board heads and four Barco flat panels connected. Those panels have an internal optical sensor.
This is the MediCal Pro configuration corresponding to the medical viewing station shown above. To run Q/A tasks on the viewing station or to perform actions on the viewing station displays, MediCal Pro must know the exact and complete configuration.
Page 34
Choose the setup type that corresponds to the viewing station on which MediCal Pro is installed: A system with CRT displays, a system with with flat panel displays or a Dicom Theater system. Click on the Next button to proceed.
Page 35
3 Searching for Barco displays The Wizard looks if there are Barco displays or projectors connected to the workstation computer via serial data connection. After a few seconds, it returns the number of found Barco displays. Notes: In case Barco flat panel displays are connected to the workstation, the Wizard can identify the display serial numbers and the heads they are connected to.
Page 36
Click on Next to continue. Please continue with step 5. 4b The number of found Barco displays does not equal the number of imaging board heads in the viewing station The Wizard asks if the number of found Barco displays really equals the number of Barco displays you want to add to the configuration.
Page 37
Select the head of which the character appears on the dimmed display. Click on the Next button to add the next display. Repeat this until all Barco displays are added. If you add Barco displays only, please continue with step 9.
Page 38
6 Position sensor patch This screen appears only in case of a Dicom Theater application. After a projector is found to add to the configuration, the projector projects a black square. This is the patch for the optical sensor (the patch will turn white afterwards).
Page 39
7 Control non-Barco displays If there are more heads in the computer than found Barco displays or if no Barco displays were found at all, the Wizard asks if you want to add non- Barco displays to the configuration. You can proceed with the Wizard, defining the non-Barco displays.
Page 40
The Wizard allows to logically link a non-Barco display to each remaining imaging board head. The Wizard makes a suggestion of the head to link the display to by inverting the colors of the character in the display’s lower right corner.
Page 41
10 Display function Select the display function you want to use for all the displays. This screen does not appear for Dicom Theater applications. Display function Select the required display function from the drop-down list. For most medical viewing applications, we recommend you select the DICOM display function, as this function results in the most visible grayscales.
Page 42
11 White and black luminance You can choose to specify one particular white luminance and black luminance value for all the displays. This screen does not appear for Dicom Theater applications. Select Yes only if all displays are the same type and if you are sure about the value to specify.
Page 43
12 Calibration You can choose to calibrate the displays and possibly run a QA check on the displays after finishing the Wizard. The Q/A check option can be checked only if the Calibrate option is checked. We advise not to check either of these options at this time, because the displays have to be aligned (CRT displays only) after the configuration setup, and the presets still have to be defined or edited.
The display icons are now filled in in the main window’s Configuration section. Note: If MediCal Pro was installed for CRT displays and the Wizard has now detected only Barco flat panel displays, a message appears, asking you to disable the Uniformity task for the flat panel displays. We advise to select Yes because the uniformity task is not needed for flat panels.
Page 45
The Wizard provides two ways to solve a search problem, taking the above-mentioned possible causes into account. Note: The search error solving methods can work only for Barco CRT displays connected through a serial connection. For flat panel or non-Barco displays these methods are not applicable.
Page 46
2 The Wizard indicates the maximum number of Barco displays you can add. This is the number of imaging board heads in the computer. In the field, enter the total number of Barco displays you want to add. This number should not exceed the number given by the Wizard.
Page 47
E.g., if 4 Barco displays are connected, you need to unplug the Remote Out connection of the 3rd one. When ready, click on Next. 7 You have to repeat the previous step on the other Barco displays, in descending order towards the computer. Read and follow the instructions of the Wizard carefully.
2 Barco flat panel displays are added immediately. For all other display types, the Display Connection Setup dialog appears. a) Select the Serial port tab if you want to add a Barco projector connected to the serial (Remote) bus. First installation...
The image of the selected display will blink for a few times. b) Select the No Link tab if you want to add a non-Barco display. Enter the brand name, type and serial number. Also, you have to indicate whether the display is a grayscale display or not, and a CRT or flat panel display.
Page 50
Non-Barco displays must be aligned using their own controls. Please refer to that display’s user documentation. To start display alignment for Barco displays, right-click on the icon of the display you want to align. Select Alignment... from the drop-down menu.
The possible display alignment families are: Horizontal geometry settings Vertical geometry settings East-West geometry settings White uniformity settings (on color displays only) The Alignment dialog contains the following elements: • The icons at the top of the dialog indicate the different alignment families (e.g., horizontal geometry, vertical geometry etc.).
Horizontal geometry settings Horizontal position (course) Position the middle vertical line of the test image approximately in the center. This is a course adjustment. You will get the opportunity to fine- tune later in the procedure. Screen width Adjust the width of the white frame on the test image following the display’s specifications.
Rotation Adjust until the white frame on the test image is perfectly upright. Vertical geometry settings Vertical position (course) Position the middle horizontal line of the test image approximately in the center. This is a course adjustment. You will get the opportunity to fine- tune later in the procedure.
bright ascending line (joined by two parts of gray lines) and two dim ascending lines, at a distance of a few cm. The bright line is the AWS line and the dim lines are AKB lines. 5. Step by step, decrease the AKB shift adjustment. As a result, the AWS and AKB lines in the test image move up.
White uniformity settings (on color displays only) The white uniformity adjustments compensate for the effect of disturbing magnetic fields on color displays. These magnetic fields cause color purity or white uniformity errors. The most common is distortion due to the earth magnetic field.

You can calibrate Barco displays and non-Barco displays, but the procedure for both categories is different. MediCal Pro supports the following sensors for calibration: X-Rite DTP92 (serial or USB), Wellhofer Luxor LXPlus, Solar PMA2200, Minolta LS100 and Tektronix TJ17. Also the Coronis I-Guard sensor inside BARCO flat panel displays and the I-Guard sensor from Dicom Theater are supported.
Calibrating Barco flat panel displays Barco flat panel displays, like the Coronis displays, have a built-in optical sensor that communicates with MediCal Pro. The calibration runs completely automatically. When the calibration is finished successfully, it displays the following message. Click on OK to close the window.
Calibrating Barco CRT displays 1 If you use an X-Rite DTP92 sensor, you may be asked to calibrate the sensor first. Make sure the sensor is completely covered (so that no light can enter the sensor) and click on OK.
Click on OK to close the window. Full screen calibration Full screen calibration is possible on Barco CRT displays only. The optical sensor must be connected to the display to be able to perform full screen calibration. The function is grayed if not available on the display.
